Our School's E.T.

Our School's E.T. is a 2008 South Korean comedy-drama film directed by Park Kwang-chun (also known as K.C. Park). It stars Kim Su-ro as an unconventional, "alien-like" high school P.E. teacher whose position is put at stake when the school adopts a new policy to boost English education, so he decides that becoming an English teacher (E.T.) overnight is his only hope.

Synopsis
Chun Sung-geun (Kim Su-ro) is the gym teacher of a private high school in an upscale district where competition is heated among students to enter top colleges. Called "E.T." by his students because of his quirky appearance and behavior, he is a teacher who has lived life his own lazy, ignorant way for years without any worries. But one day he's hit with a crisis: At the school's board meeting, a parent requests that the school get rid of "useless" gym classes and expand the hours for English classes. The school decides to hire another English teacher— at the cost of a gym teacher. In danger of losing his position, he remembers by chance that he obtained a license to teach English a decade ago. The school board president tells him to pass a test in order for her to acknowledge it. So Sung-geun, who hasn't spoken (much less taught) English for ten years, faces the near-impossible task of becoming an English teacher within two weeks. His only weapon is his amazingly incomparable physical strength, and with the help of a few students who understand his warm heart, the simpleton Sung-geun begins his rigorous training to exercise his brain "muscles" to master English in his journey to become the school's E.T.
